We'll all be swimming naked soon

This week's edition of The Economist magazine offers an ominous warning for the U.S. economy in the article Danger Time For America.

The Economist has long criticised Mr Greenspan for not trying to restrain the stockmarket bubble in the late 1990s, and then, after it burst, for inflating a housing bubble by holding interest rates low for so long (see article). The problem is not the rising asset prices themselves but rather their effect on the economy. By borrowing against capital gains on their homes, households have been able to consume more than they earn. Robust consumer spending has boosted GDP growth, but at the cost of a negative personal saving rate, a growing burden of household debt and a huge current-account deficit.

When house-price rises flatten off, and therefore the room for further equity withdrawal dries up, consumer spending will stumble. Given that consumer spending and residential construction have accounted for 90% of GDP growth in recent years, it is hard to see how this can occur without a sharp slowdown in the economy.

Handovers to a new Fed chairman are always tricky moments. They have often been followed by some sort of financial turmoil, such as the 1987 stockmarket crash, only two months after Mr Greenspan took over. This handover takes place with the economy in an unusually vulnerable state, thanks to its imbalances. The interest rates that Mr Bernanke will inherit will be close to neutral, neither restraining nor stimulating the economy. But America's domestic demand needs to grow more slowly in order to bring the saving rate and the current-account deficit back to sustainable levels. If demand fails to slow, he will need to push rates higher. This will be risky, given households' heavy debts. After 13 increases in interest rates, the tide of easy money is now flowing out, and many American households are going to be shockingly exposed.

In the words of Warren Buffett, “It's only when the tide goes out that you can see who's swimming naked.”
